Abstract
The utility model discloses an exhaust pipe connecting structure of a refrigeration compressor, comprising a pump body, a shell body, an inner exhaust pipe and a sealing pipe, wherein the pump body is provided with an air suction hole, the shell body is provided with an exhaust pipe, an air suction pipe and a process pipe, the inner exhaust pipe is made of flexible nylon material and is respectively connected with the pump body and the exhaust pipe, and the inner exhaust pipe is connected with the exhaust pipe in a sealing way after being sheathed by the sealing. Due to the flexible connection between the pump body and the exhaust pipe, the spread impedance of energy from the pump body to the shell body is increased, thereby effectively controlling the noise and vibration of the compressor.
Description
Technical field
The utility model relates to the refrigeration compressor field, specifically a kind of exhaust pipe connection structure of refrigeration compressor.
Background technique
Noise is the important indicator of evaluation refrigeration compressor performance with vibrating, and realizes the noise reduction and the vibration damping of compressor at present usually from two aspects, the one, and the energy of minimizing sound source and vibration source, the 2nd, the impedance of raising propagation path.Compressor exhaust pipe is one of main path of borne noise and vibration, therefore generally all is noise reduction and the vibration damping of realizing compressor through the design of optimizing outlet pipe.The exhaust pipe connection structure of existing refrigeration compressor is as shown in Figure 1; Comprise the pump housing 1, housing 2 and inside exhaust pipe 7, the pump housing 1 is provided with intakeport 5, and housing 2 is provided with outlet pipe 3, sucking pipe 4 and process duct 8; Inside exhaust pipe 7 is provided with shock-absorbing spring 6, and inside exhaust pipe 7 is connected with outlet pipe 3 with the pump housing 2.During compressor operating, low-pressure gas gets into the pump housing 2 through sucking pipe 4, intakeport 5, after the pump housing 2 compressions, becomes pressurized gas, and discharges through inside exhaust pipe 7, outlet pipe 3.Inside exhaust pipe 7 is processed with outlet pipe 3 usefulness metal tubes, adopts welding manner continuous (as shown in Figure 2) between inside exhaust pipe 7 and the outlet pipe 3.Because the rigidity of metal tube is stronger; Be easy to generate noise and vibration in the transmittance process; Although at present inside exhaust pipe 7 is often through adopting complicated shape, increase length, measure such as shock-absorbing spring is set reduces noise and transfer of vibration; But because of the transmission capacity of noise and vibration in the metal tube transmittance process is stronger, propagate into housing from the pump housing easily, the noise of compressor still is difficult to control with vibration.
Summary of the invention
The utility model technical problem to be solved is to propose a kind of exhaust pipe connection structure that can significantly reduce the refrigeration compressor of noise and vibration propagation.
For solving the problems of the technologies described above; The exhaust pipe connection structure of the utility model refrigeration compressor comprises the pump housing, housing, inside exhaust pipe and sealed pipe; The said pump housing is provided with intakeport, and said housing is provided with outlet pipe, sucking pipe and process duct, and said inside exhaust pipe adopts the flexible nylon material to process; And link to each other with outlet pipe with the said pump housing respectively, link to each other with said outlet pipe sealing behind said the above sealed pipe of inside exhaust pipe cover.
The exhaust pipe connection structure of above-mentioned refrigeration compressor, it also comprises elastic ring and seal ring, and said sealed pipe adopts elastic plastic material to process, and which is provided with locating slot and seal groove, and said elastic ring and seal ring are located at respectively in said locating slot and the seal groove.
The exhaust pipe connection structure of above-mentioned refrigeration compressor, said outlet pipe are provided with positioning groove and end face taper hole, and the angle of said end face taper hole is 0～90 °.
The utility model is realized between the pump housing and the outlet pipe flexibly connecting owing to adopt technique scheme, has improved the propagation impedance of energy from the pump housing to the housing, thereby the noise of compressor can be effectively controlled with vibration.
